水泥砂浆地面起砂的原因很多,主要是操作不当,养护不好,水泥标号低等。我们使用107胶水泥腻子,满刮在起砂的地面上,以解决水泥地面起砂的问题,取得了一定的效果。一、水泥地面起砂修理的试验 1.腻子的遍数与硬度试验:用80目砂纸打磨的试验结果如表1所示。 2.腻子表面加刷107胶一度的耐磨试验:用70目砂纸打磨的试验结果如表2所示。 3.107胶水泥腻子修理地面或作地面装饰,有107胶表面涂层者的耐水磨性能远优于无107胶表面涂层者(表3)。 There are many reasons for sanding on the surface of cement mortar, mainly due to improper operation, poor maintenance, and low cement number. We used 107 cement putty, full of scraping on the sanded ground to solve the cement floor sanding problem, and achieved certain results. First, the cement floor sand repair test 1. Putty’s number of times and hardness test: 80 mesh sandpaper test results shown in Table 1. 2. Putty of 107 rubber on the surface of the putty was once worn. The test results of grinding with 70-grit sandpaper are shown in Table 2. 3.107 cement putty to repair the ground or as a floor decoration, 107 gel surface coating of water resistance is much better than those without 107 gel surface coating (Table 3).
